Windows 8.1 now up to 3.95% market share as it passes Vista, Windows 8 falls to 6.63%

TNW- With the release of Windows 8.1 to the world in October, January was the third full month of availability for Microsoft’s latest operating system version, which was just enough time for it to pass Windows Vista in market share. While Windows 8.1 is certainly growing steadily and eating into Windows 8′s share, the duo only managed to end 2013 with 10 percent market share, barely impacting Windows 7.
